Abstract
Due to the emergence of drug-resistant microorganisms, treating infectious illnesses is a significant challenge in the medical industry. To counter this, researchers are continuously investigating new drugs to combat infectious illnesses. Hence, we explore the production of new SB derivatives (SB1–SB8) obtained from the condensation of 5-hydroxysalicyaldehyde with substituted amines. For structural confirmations of procured compounds, Fourier-transform infrared spectroscopy, 1H and 13C-Nuclear magnetic resonance, single crystal X-ray diffraction, and electrospray ionisation mass spectrometry spectroscopic methods of analysis were employed. The SCXRD analysis of compound SB1 has a triclinic lattice with P-1 and Z = 2 space groups. The antimicrobial attributes of synthesized SB derivatives (SB1–SB8) were further investigated. In comparison with conventional antibiotic ampicillin (250 and 100 µg/mL), the compound SB3 demonstrated enhanced effectiveness against S. aureus (100 µg/mL), E. coli (62.5 µg/mL), and S. pyogenes (50 g/mL), as well as euipotency against the P. aeruginosa (100 µg/mL) microorganisms. Among the synthesized compounds, compounds SB1 and SB5 to SB8 showed notably greater potency (100–250 µg/mL) against the fungus C. albicans in comparison to the conventional drug Griseofulvin (500 µg/mL).
